Which of these activities performed by a chemist is primarily based on an understanding of physics? A. using an indicator to determine if a solution is an acid, base, or neutral B. testing the molar concentration of a solution C. checking whether a given element is a metal or nonmetal D. predicting the volume of a gas, given its temperature and pressure

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

the components of a vector are the parts of the vectors that are to each other.
